Rollup merge of #89591 - infinity0:master, r=Amanieu

fix: alloc-optimisation is only for rust llvm

As discussed at the bottom of #83485.

On a separate note I'll take this chance ask, is it worth pulling in that patch (to recognise `__rust_dealloc`) into Debian's system LLVM? The main factors for us to consider would be (1) is the optimisation significant and (2) is there not any significant negative impact to non-rust packages that use LLVM.
